Researchers have found a solution to the problem of overheating of active plasmonic components. They demonstrate how to efficiently cool optoelectronic chips using industry-standard heatsinks in spite of high heat generation in active plasmonic components.

Using strands of nucleic acid, scientists have demonstrated basic computing operations inside a living mammalian cell. The research could lead to an artificial sensing system that could control a cell's behavior in response to such stimuli as the presence of toxins or the development of cancer.

A new class of small, thin electronic sensors can monitor temperature and pressure within the skull - crucial health parameters after a brain injury or surgery - then melt away when they are no longer needed, eliminating the need for additional surgery to remove the monitors and reducing the risk of infection and hemorrhage.

The very first experimental observations of knots in quantum matter have just been reported. The scientists created knotted solitary waves, or knot solitons, in the quantum-mechanical field describing a gas of superfluid atoms, also known as a Bose-Einstein condensate.

Maybe soon we can say goodbye to polystyrene, the petroleum-based material that is used to make Styrofoam. In what looks like an ordinary bicycle helmet, designers have replaced Styrofoam with a new shock-absorbing material made with renewable and biodegradable wood-based material.

Focusing the laser was conducted with the help of small glass spheres, playing the role of the lens. This mechanism allows inexpensively and relatively easy to apply complex patterns to a glass surface, whereby obtaining a spatial resolution of less than 100 nanometers.
